5y-3/2y+1=2/5
In solving method
Answers
Step-by-step explanation:
5y-3/2y+1=2/5
use the cross multiplication method
5(5y-3)=2(2y+1)
=25y-15=4y+2
=21y=17
y=17/21
Answer:
The answer to the qusetion is 17/21.
Step-by-step explanation:
In such kinds of questions we use cross multiplication method. Cross multiplication method is used when two fractions are given and seperated by equal signs. In some questions, we come across such equation which have fractions on both right and left side and in between the fractions, equal sign is given. Here , in this case we cross multiple the numerator to denominator of each other.
For example 3/5 = 2/4 , this is a question which need cross mutliplication method to get solution.
The given question is
5y-3/ 2y+1 = 2/5
5(5y-3) = 2( 2y+ 1)
25y- 15 = 4y + 2
25y - 4y = 2 + 15
21y = 17
y = 17/21
The value of y is 17/21.
